Temperature Control Network
• Using the temperature control network, the V7 series can be connected to the
temperature controller. With RS-232C, one PLC can be connected; with RS-485, a
maximum of 31 temperature controllers can be connected.
maximum of 31 temperature controllers can be connected.
• Data of temperature controllers connected to the V7 series can be set or monitored.
• Periodical reading/sampling of temperature controller data
Temperature controller data can be read into the PLC memory or V7 internal memory at
regular intervals using the temperature control network table. It is also possible to save
the read data in the V7 internal buffer, SRAM or CF card.

• Data transfer
It is also possible to transfer data in the PLC memory, V7 internal memory or a memory
card to the temperature controller at one time using a macro command. Conversely,
data in the temperature controller can be transferred to the PLC memory, V7 internal
memory or a memory card at one time.
